When hazardous gases meet precise airflow control, who guards the final line of industrial safety?

In oil refineries, nuclear power plants, pharmaceutical workshops… every direction of airflow is a matter of life and death. Explosive gases, high-temperature steam, combustible dust—these “invisible beasts” lurk in the corners of industrial environments. And the damper actuators within HVAC systems are the first line of defense against them.

If an actuator fails, the consequences could be severe — from costly production interruptions to, in the worst case, a major disaster.

Certified for Global Use:

The ExS6061Pro Series has obtained four authoritative explosion-proof certifications:

• China CCC certification
• EU ATEX certification
• International IECEx certification
• Russia EAC certification

One actuator simultaneously meets the stringent explosion-proof standards of China, Europe, the international community, and the Eurasian Economic Union.

Ex marking: Ex db ⅡC T6 Gb / Ex tb ⅢC T85℃ Db This means it can operate stably in environments containing Class ⅡC explosive gases (hydrogen, acetylene, etc.—the most dangerous rate) and Class ⅢC conductive dust, with surface temperature strictly controlled to T6 (≤85℃).

• Product Core Highlights: 

More than just explosion-proof—precision and reliability

Wide torque coverage, adaptable to various dampers

SF Series (Spring return): 5Nm, 10Nm, 15Nm, 20Nm, 30Nm, 40Nm

NS Series (Non-spring return): 10Nm, 20Nm, 30Nm, 40Nm

• Two control types, flexible for on-site needs

On/Off: Simple, direct, fast response

Modulating: 0(2)-10V or 0(4)-20mA analog signal control for precise opening adjustment

•  Strong power supply compatibility

AC/DC 24V (wide range 19.2–28.8V)

AC 220V (110–240V)

• Spring return, safe positioning upon power failure

AFK / DFK-3: Spring return time ≤3 seconds

DFK-1: ≤1 second (emergency shutdown scenarios)

Even if the main power fails, the damper closes or opens instantly, cutting off hazardous sources or initiating exhaust.

• IP66 protection, defying harsh environments

Operating temperature: -30℃ to +60℃

Storage temperature: -40℃ to +70℃

Humidity: 5–95% RH

Protection rating IP66—resistant to heavy rain, powerful water jets, and complete dust ingress

• Long life, low maintenance

Spring return types (AFK, DFK-3): ≥10,000 cycles

Fast shutdown type (DFK-1): ≥1,000 cycles (optimized for emergency scenarios)

• Typical application scenarios

✔ Oil & gas processing platforms ✔ Petrochemical refining units ✔ Ship hazardous compartment ventilation ✔ Thermal power plants, nuclear power plant ventilation systems ✔ Pharmaceutical workshops (including solvent evaporation) ✔ Metallurgical plant dust environments ✔ Painting booths, chemical warehouses

Use an actuator that has proven itself on the global stage — and safeguard your explosion-proof critical line.

The Soloon ExS6061Pro Series is not an ordinary actuator. It is a safety veteran that has passed the quadruple explosion-proof tests of China, the EU, the international community, and Russia. It is a reliable partner that continues to precisely control airflow in conditions ranging from -30℃ bitter cold to 60℃ heat, in combustible dust and hydrogen environments. It is the last line of defense that resets within 1 second upon power failure, protecting critical ventilation paths.
